Skype, Messenger, etc: I drop packets on the network with the expectation that the recipient will get them with consistent sub-second delays. (Most of them. Usually in order. Depending on the reuqirements of the application.)
What’s the model for this kind of communication on the safe network? It’s basically a two-way stream between two nodes (could be extended to more, e.g. for group chats or group calls), sometimes with TCP-like requirements (e.g. chat), sometimes with UDP-like requirements (e.g. phone, video, etc). The packets are transient; they are not stored once transmitted. I can’t recall anything like this on the safe network, but I may be ignorant.
Lag? My concern is that nodes can’t address each other by IP address, so the routing layer will pass around my little hello’s and goodbye’s in addition to what’s happening on the IP layer. I’m wondering how much delay it will introduce.
Bandwidth? Similarly, can we expect that the additional layer won’t introduce bottlenecks? Regular routing nodes, unlike core routers on the internet, can not be expected to have hideously high throughput. I’m aware (old) Skype managed to figure this out, so it’s for sure not impossible.
